Senior AWS Cloud Engineer (Serverless & Technical Ownership)

### 🧭 Overview We are looking for a **Senior AWS Cloud Engineer** with strong hands-on experience in **Python and serverless architectures**, capable of **owning technical solutions end-to-end**. This is not a task-execution role. We are looking for someone who can **analyze requirements, make technical decisions, and evolve existing systems in production environments**. You will primarily work on **AWS-based serverless systems already in place**, focusing on: * Enhancements and feature evolution * New integrations * Performance, scalability, and reliability improvements Strong coding ability is essential — particularly in **Python for backend and serverless development** — combined with the ability to understand and improve system design. ### 🚀 Key Responsibilities * Design and implement **serverless solutions in AWS**, mainly using Lambda, API Gateway, and event-driven services. * Take **ownership of technical decisions**, including architecture, scalability, performance, and cost trade-offs. * Work on **existing systems**, extending and improving services based on real business needs. * Translate functional requirements into **well-structured technical solutions**, not just code execution. * Build and maintain backend logic using **Python**, including integrations, data processing, and service orchestration. * Implement and maintain **event-driven architectures** (e.g., Kafka, SNS, EventBridge). * Ensure proper **error handling, observability, and system reliability** in distributed environments. * Collaborate with backend, DevOps, and business teams to deliver robust solutions. * Contribute to **technical discussions and architectural decisions**, even within pre-existing systems. * Follow and evolve **existing patterns and best practices**, not reinvent unnecessarily. ### 🧩 Required Experience * 5+ years of experience in backend or cloud engineering roles. * Strong hands-on experience developing backend or serverless solutions using **Python** (e.g., APIs, integrations, data handling, AWS SDK/Boto3). * Proven experience working with **AWS serverless services in production**, particularly: * Lambda * API Gateway * DynamoDB * S3 * * Experience working with **event-driven systems**, understanding asynchronous flows and distributed processing. * Experience contributing to or influencing **architecture decisions**, especially in serverless or cloud-native systems. * Solid understanding of **microservices architecture**, including when to use it vs serverless or monolithic approaches. * Experience handling real production challenges such as: * Timeouts and long-running processes * Data processing at scale * Service-to-service communication * ### ⚙️ Technical Expectations Candidates must demonstrate: * Ability to **design solutions**, not only implement tasks * Understanding of **architecture trade-offs** (cost, scalability, performance) * Experience working with and improving **existing systems**, not only building from scratch * Practical knowledge of **IAM and security best practices** (e.g., least privilege applied in real scenarios) * Experience working with CI/CD pipelines, including understanding deployment flows and making adjustments when needed. ### 🧠 Nice to Have * Experience implementing **ETL processes** in serverless environments * Familiarity with tools like **Terraform, CDK, or CloudFormation** * Exposure to **GraphQL or gRPC** * Experience in **financial or regulated environments** ### 🧭 Working Style (Critical for this Role) We are looking for someone who: * Works with a high level of **autonomy** * Takes **ownership of problems and solutions**, not just assigned tasks * Is comfortable making **technical decisions without constant supervision** * Proactively identifies opportunities to improve systems and architecture 🚨 This is NOT a role for candidates who only execute tickets or depend heavily on direction. ### 🌍 Communication * 🌍 Languages * **English: Intermediate.** * Collaboration with international teams may be needed ### ⚠️ What This Role Is NOT * Not a junior or mid-level execution role * Not limited to coding tasks or ticket-based development * Not a purely DevOps or infrastructure-focused role 🚀 Integration into global brands and disruptive startups. 🏡 Remote work / Home office. 📍 If a hybrid or on-site modality is required, you will be informed from the first interview. ⏳ Schedule aligned with the assigned project or work cell. 📅 Monday to Friday work schedule. 🎉 Day off on your birthday. 🏥 Major medical expenses insurance (applicable in Mexico). 🛡️ Life insurance (applicable in Mexico). 🌎 Multicultural work teams. 🎓 Access to courses and certifications. 📢 Meetups with special guests from the IT industry. 📡 Virtual team-building events and interest groups. 📢 English classes. 🏆 Opportunities across our different business lines. 🏅 Proudly certified as a Great Place to Work.
